8+ ph Alkaline soil


Question
The soil on our newly purchased land has a high alkaline pH, 8+ on a soil test kit - how can we properly prepare our soil for veggies, flowers, and trees?  Neighbors say use Gypsum - I've read articles that say not to use that additive - please advise.  Thanks

Answer
Hi Patti, I would not use gypsum.  It can turn clay into muck.  I'd use iron sulfate (copperas), aluminum sulfate or sulfur to lower the pH to 7 or just below.  Follow the label instructions for quantity and coverage.  I'd take a soil sample to your local independent nursery.  Many will test your pH for free and I'd get a second reading before adjusting anything.  I've seen some questionable results from some test kits.  An inexpensive pH meter is usually very close to correct.  Jim
